High sulphidity pulping process : An alternative to the kraft pulping process

Kraftmassaprocessen är den dominerade massaframställningen bestående av 90% av världens kemiska jungfrumassa. Denna process är omfattande och förbättringar pågår ständigt, särskilt med tanke på den stora kemikalieåtervinningen [1]. 1966 publicerade G.H. Tomlinson II ett patent där en vitlut av 100% sulfiditet användes, alltså endast natriumsulfid (Na2S)
